It is interesting, in regard to biology, that eggs of the cod were found, 

 drifting in great quantities, 8 miles to the Westward of Utsire (see Chart of 

 Depths II). 



During the Winter iSgs-> but a sparse amount of Plankton was met 

 with in the South, consisting, as a rule, of Cilioflagellata and a few 

 kinds of Larvae. On the 25th February, fishes' eggs were found, as well 

 as a great number of HalospJiœra viridis, and one Chlorophycea. It was 

 odd that species of Coscinodiscus, which had been so numerous the pre- 

 vious year, were entirely absent. 



I dare not give an opinion as to what extent the difference between 

 the Plankton of the Winter of 1894, and that of 1895, has been occa- 

 sioned by the hydrographical conditions. It is important to observe in 

 1895, the quantity o^ Cilioflagellata, and the paucity of animal Plankton; 

 in 1894, the numerous Calanida and Coscisnodisais'^. 



The Spring of 1894, during which period a great many of the pre- 

 sent specimens were obtained, was distinguished by an abundance of 

 Plankton, which, as is shewn in the Table, consisted of most numerous 

 kinds of larvæ, and young individuals of various orders. To these must 

 be added great quantities of Cilioflagellata. 



In the North, at Vigten, Calanida, especially Calanus finmarchiciis 

 as well as Cilioflagellata were found. The appearance of Halosphœra 

 and Actinactis was of biological interest.
